Attorney Ro Khanna, a Democrat seeking to defeat longtime Rep. Michael M. Honda, D-Calif., has started to air his second advertisement of the race — a sign the challenger is becoming more aggressive ahead of a June primary.

In the 30-second ad, released on Monday, Khanna broadly describes a few of his policy proposals if elected to Congress. For example, he suggests adding computer coding to the curriculum in public schools – an issue that could resonate in the Silicon Valley-based 17th District.

Khanna, Honda, Republican physician Vanila Singh and a handful of other lower-tier candidates will face off in a "jungle" primary on June 3. The top two vote recipients, regardless of party, will advance to the general election in November.

Khanna's campaign did not immediately return a request for information on where and when the ad will air. Khanna's campaign will report nearly $2 million in the bank as of March 31, giving him ample funds for advertising.
